Page 204.1.2 MountingWhile mounting the inverter, take care to placethe inverter in a location and orientation thatallows for access to both cooling portconnections and electrical connections asprotected by the gasket plate. MA3 inverters aretypically mounted with legs and/or spacers at the four (4)M10 mounting points on 250 mm (9.84″) x 300 mm (11.81″) centers.4.1.3 Installation OrientationThe MA3 inverter can be installed in any orientation. It has no preferred orientation formounting. The installer must exercise care so that debris will not build up between the inverterhousing and mounting surfaces. Debris buildup degrades cooling of the device, and may have apossible impact of freezing to the device casing. Assume the standard axis configurationwhenever this document refers to it.4.2 Cooling RequirementsThe MA3 inverter is enclosed in an IP65-rated aluminum casting that has an embedded coolingsystem capable of using ethylene glycol- or hydraulic oil-based coolants.Details of the inverter cooling system requirements using pre-diluted ethylene glycol (EG) (50%EG, 50% water) and temperature ratings are presented in the following table.
